Constructs a new instance of the FirelensLogRouter class.

Parameters:

scope (Construct)
id (str)
firelens_config (Union[FirelensConfig, Dict[str, Any]]) – Firelens configuration.
task_definition (TaskDefinition) – The name of the task definition that includes this container definition. [disable-awslint:ref-via-interface]
image (ContainerImage) – The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest. TODO: Update these to specify using classes of IContainerImage
command (Optional[Sequence[str]]) – The command that is passed to the container. If you provide a shell command as a single string, you have to quote command-line arguments. Default: - CMD value built into container image.
container_name (Optional[str]) – The name of the container. Default: - id of node associated with ContainerDefinition.
cpu (Union[int, float, None]) – The minimum number of CPU units to reserve for the container. Default: - No minimum CPU units reserved.
disable_networking (Optional[bool]) – Specifies whether networking is disabled within the container. When this parameter is true, networking is disabled within the container. Default: false
dns_search_domains (Optional[Sequence[str]]) – A list of DNS search domains that are presented to the container. Default: - No search domains.
dns_servers (Optional[Sequence[str]]) – A list of DNS servers that are presented to the container. Default: - Default DNS servers.
docker_labels (Optional[Mapping[str, str]]) – A key/value map of labels to add to the container. Default: - No labels.
docker_security_options (Optional[Sequence[str]]) – A list of strings to provide custom labels for SELinux and AppArmor multi-level security systems. Default: - No security labels.
entry_point (Optional[Sequence[str]]) – The ENTRYPOINT value to pass to the container. Default: - Entry point configured in container.
environment (Optional[Mapping[str, str]]) – The environment variables to pass to the container. Default: - No environment variables.
environment_files (Optional[Sequence[EnvironmentFile]]) – The environment files to pass to the container. Default: - No environment files.
essential (Optional[bool]) – Specifies whether the container is marked essential. If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, then its failure does not affect the rest of the containers in a task. All tasks must have at least one essential container. If this parameter is omitted, a container is assumed to be essential. Default: true
extra_hosts (Optional[Mapping[str, str]]) – A list of hostnames and IP address mappings to append to the /etc/hosts file on the container. Default: - No extra hosts.
gpu_count (Union[int, float, None]) – The number of GPUs assigned to the container. Default: - No GPUs assigned.
health_check (Union[HealthCheck, Dict[str, Any], None]) – The health check command and associated configuration parameters for the container. Default: - Health check configuration from container.
hostname (Optional[str]) – The hostname to use for your container. Default: - Automatic hostname.
inference_accelerator_resources (Optional[Sequence[str]]) – The inference accelerators referenced by the container. Default: - No inference accelerators assigned.
linux_parameters (Optional[LinuxParameters]) – Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities. Default: - No Linux parameters.
logging (Optional[LogDriver]) – The log configuration specification for the container. Default: - Containers use the same logging driver that the Docker daemon uses.
memory_limit_mib (Union[int, float, None]) – The amount (in MiB) of memory to present to the container. If your container attempts to exceed the allocated memory, the container is terminated. At least one of memoryLimitMiB and memoryReservationMiB is required for non-Fargate services. Default: - No memory limit.
memory_reservation_mib (Union[int, float, None]) – The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. At least one of memoryLimitMiB and memoryReservationMiB is required for non-Fargate services. Default: - No memory reserved.
port_mappings (Optional[Sequence[Union[PortMapping, Dict[str, Any]]]]) – The port mappings to add to the container definition. Default: - No ports are mapped.
privileged (Optional[bool]) – Specifies whether the container is marked as privileged. When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). Default: false
readonly_root_filesystem (Optional[bool]) – When this parameter is true, the container is given read-only access to its root file system. Default: false
secrets (Optional[Mapping[str, Secret]]) – The secret environment variables to pass to the container. Default: - No secret environment variables.
start_timeout (Optional[Duration]) – Time duration (in seconds) to wait before giving up on resolving dependencies for a container. Default: - none
stop_timeout (Optional[Duration]) – Time duration (in seconds) to wait before the container is forcefully killed if it doesn’t exit normally on its own. Default: - none
system_controls (Optional[Sequence[Union[SystemControl, Dict[str, Any]]]]) – A list of namespaced kernel parameters to set in the container. Default: - No system controls are set.
user (Optional[str]) – The user name to use inside the container. Default: root
working_directory (Optional[str]) – The working directory in which to run commands inside the container. Default: /

Methods

add_container_dependencies(*container_dependencies)

This method adds one or more container dependencies to the container.

Parameters:: container_dependencies (ContainerDependency)
Return type:: None

add_environment(name, value)

This method adds an environment variable to the container.

Parameters:

name (str)
value (str)

Return type:

None
